Punch forming system 1 is made of these the 1st vertical 3 grades of decompressors 2, the 2nd vertical 3 grades of decompressors 3, pay-off 4 and conveyer 7.

Next a series of actions for punch forming system 1 is illustrated.At first stored material M transmits and is arranged on the 3rd counterdie 60 of the 3rd mould 34 to the 1st vertical 3 grades of decompressors 2 via two arms 5,6 on the pay-off 4.At this moment, as mentioned above, oil is coated on the desired position on the material M.

Then, set this material M is shaped to by the 3rd mould 34 after the material M1, is arranged at by arm (not shown) on the 2nd counterdie 56 of the 2nd mould 32.Follow set this material M1 and be shaped to after the material M2 by the 2nd mould 32, be arranged at by arm (not shown) on the 1st counterdie 52 of the 1st mould 30.

Then, set this material M2 is shaped to by the 1st mould 30 after the material M3, is arranged at by conveyer 7 on the 3rd counterdie 60 of the 3rd mould 34 of the 2nd vertical 3 grades of decompressors 3.At this moment, as mentioned above, conveyer 7 possesses towards the change function, therefore can with material M3 with the 2nd vertical 3 grades of decompressors 3 required towards transmitting.

Then, set this material M3 is shaped to material M4 (not shown) afterwards by the 3rd mould 34, is arranged at by arm (not shown) on the 2nd counterdie 56 of the 2nd mould 32.Then, set this material M4 is shaped to material M5 (not shown) afterwards by the 2nd mould 32, is arranged at by arm (not shown) on the 1st counterdie 52 of the 1st mould 30.

At last, set this material M5 is shaped to workpiece (the not shown product of finishing) afterwards by the 1st mould 30, takes out by arm (not shown).Be for example in the situation of the Punching Technology of material M5 workpiece is die-cut (cut-out) in this moulding, also can die-cutly punch out other parts that are different from this workpiece from the position that material M5 becomes waste material (defective material) simultaneously with this.Thus, can immediately waste material effectively be utilized.So through 6 molding procedure, M produces workpiece from material.

In addition, in the explanation of this action, the material M that is arranged on the 3rd counterdie 60 of the 3rd mould 34 of the 1st vertical 3 grades of decompressors 2 is shaped to after the material M1 by the 3rd mould 34, when being arranged on the 2nd counterdie 56 of the 2nd mould 32 by arm (not shown), at the 3rd counterdie 60 of the 3rd mould 34 new material M is set.Then, repeat this setting.

The 1st vertical 3 grades of decompressors 2 of embodiments of the invention consist of as mentioned above.According to this structure, the 1st mould 30, the 2nd mould 32, the 3rd mould 34 are along linking up with direction that its matched moulds/the die sinking direction is identical.And these
